Earths systems
unit 10
| Term | Definition |
|---|---|
| Earth system | Earth´s interacting physical, chemical, and biological processes. |
| geosphere | The layer of Earth made up of solid rock and other rocky materials. |
| hydrosphere | The total amount of water on a planet. |
| cryosphere | Earth's ice in all its forms. |
| atmosphere | A mixture of gases that surrounds the Earth. |
| biosphere | The biosphere is made up of living things and the areas of Earth where they are found. The rocks, soil, oceans, lakes, rivers, and lower atmosphere all support life. |
| energy budget | Earth’s energy budget is a way to keep track of energy transfers into and out of the Earth system |
| air pressure | Air pressure is the measure of the force with which air molecules push on an area of a surface. |
| thermosphere | the thermosphere is the uppermost layer of the atmosphere. |
| mesosphere | The mesosphere is between the thermosphere and stratosphere. |
| stratosphere | The stratosphere is between the mesosphere and troposphere. |
| troposphere | The troposphere is the lowest layer of the atmosphere. |
| ozone layer | The ozone layer is an area in the stratosphere, 15 km to 40 km above Earth’s surface, where ozone is highly concentrated. |
| the green house effect | The greenhouse effect is the process by which gases in the atmosphere, such as water vapor and carbon dioxide, absorb and give off infrared radiation. |
| temperature | Temperature is a measure of the average kinetic energy of particles. |
| thermal energy | Thermal energy is the total kinetic energy of particles. |
| thermal expencion | The increase in volume that results from an increase in temperature is called thermal expansion. |
| heat | Heat is the energy that is transferred between objects that are at different temperatures. |
| radiation | Radiation is the transfer of energy as electromagnetic waves. Radiation can transfer energy between objects that are not in direct contact with each other. |
| convencion | If so, you have seen convection. Convection is the transfer of energy due to the movement of matter. |
| conduction | Conduction is the transfer of energy from one object to another object through direct contact. |
| wind | the movement of air caused by differences in air pressure is called wind. |
| cariolis effect | The apparent curving of the path of a moving object from an otherwise straight path due to Earth’s rotation is called the Coriolis effect |
| global wind | Coriolis effect produce patterns of calm areas and wind systems. These wind systems occur at or near Earth’s surface and are called global winds. |
| jet stream | Jet streams are narrow belts of high-speed winds that blow from west to east, between 7 km and 16 km above Earth’s surface. |
| local wind | local winds are the movement of air over short distances. |
